Application April 28, 1955, Serial No. 504,590

(Ilaims. (Cl. 210-169) This invention relates to a rust filter or protector for spray rinse water clothes spinner-extractors.

With spinner-extractors where water is used to spray and rinse clothes, the clothes, when the rinsing and drying have been effected, will often have yellow rust streaks thereon. This has been found to be caused by the stirring up of accumulated sediment in either the water heater or storage system or in the main supply lines. If the supply is turned off over night, then opened the next day, this sediment will have accumulated and passed with the water to the spinner-extractor and is deposited on the clothes being treated therein. Even though the spinner element is formed of stainless steel, this sediment and rust apears in the bottom of the spinner element and the clothes contacting therewith receive the same and are stained.

It is accordingly an object of the present invention to provide a filter or protector for spinner-extractors which is formed of cloth and which is so shaped and reinforced as to form a cover for the bottom of the perforated spinner element or basket and to stay in the bottom while the spinning of the clothes is effected whereby to keep the clothes out of contact with the bottom of the spinning element or basket at all times.

It is another object of the invention to provide in a rust filter or protector for spinner-extractors a flexible flange projecting upwardly from the filter in the form of a flexible rim so that the filter will be held and locked in the bottom as a result of centrifugal action and positive pressure of the clothes upon the rim and wherein this rim can be folded or reversed upon the bottom of the filter to permit the filter to be inserted in the spinning element in the reversed manner and with the opposite face lying against the bottom surface of the spinner element.

Other objects of the invention are to provide a filter for spray rinse water clothes spinner-extractors having the above objects in mind which is of simple construction, has only one piece, inexpensive to manufacture, easy to insert and remove from the spinner element or basket, easy to clean, durable and has long life, compact, effective and eflicient in use.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a vertical sectional view of the rinsing and drying compartment of a washing machine with portions of the spinner element broken away toshow the rust filter therein;

Fig. 2 is an enlarged perspective view of the rust filter; and

Fig. 3 is a radial sectional view of the filter as viewed on line 33 thereof.

Referring now particularly to Fig. 1, represents a rinsing and spin drying compartment of a combined washing and drying machine 11. Other compartments of the machine have the washing elements to wash the 2,758,721 Patented Aug. 14, 1956 ice clothes and when the clothes are so washed, they are removed and upon cover 12 of the rinsing and drying compartment being elevated, the clothes are deposited in perforated spinning element or basket 13 through its top opening 14 therein. This element is formed of stainless steel and is fixed to a drive shaft 15 that is power driven at either reduced speed or high speed. On the cover 12 is a spray nozzle 16 that directs a spray through the opening 14 and onto the clothes to rinse them. This water, as explained above, usually has sediment for one reason or another which will normally deposit a rust film 17 on the bottom of the spinner element 13. This rust will be picked up by the clothes and provide undesired yellow streaks on them. The water may be drained from the compartment 10 by drain pipe 18.

In order to eliminate the rust from staining the clothes, a rust filter or protector 19 is placed upon the bottom of the spinning element, and this filter is so constructed that it will cling to the bottom of the spinning element and will not be commingled with the clothes as a result of the clothes being shifted by centrifugal action as the spinning element is driven.

The filter 19 is formed of two annular members 20 and 21 of cloth separated by filling material 22 and stretched as indicated at 23 to provide quilting assembly. An opening 24 is provided in the center of the filter through which the shaft 15 is extended and to permit the filter to surround the same. The inner peripheral edge of the cloth rings are secured together by a binding tape 25.

Extending radially outwardly from the binding 25 are a plurality of angularly spaced pocket strips 26 that respectively contain radially-extending spring stiffening or reinforcing elements 27 to give rigidity to the cloth quilting.

On the outer periphery of the annular members 20 and 21 and secured therebetween by a stitching 28 is a cotton flexible or semi-rigid self-supporting webbing or belting 29 adapted to be turned to extend upwardly and engage with the inner cylindrical surface of the spinning element. The ends of the belting are vertically joined by a binding tape 30. This belting can be turned, as illustrated in Fig. 3, and the filter reversed so that the opposite face of the quilting can rest on the surface of the basket bottom 17.

As the spinning element is spun, the clothes are thrown against the inner surface of the belting 29 so as to hold or lock the belting and the filter positively against the inner surface of the spinning element.

It should now be apparent that there has been provided a protector cover for the bottom of a spinning element of a spray water spinner-extractor to keep the clothes out of contact with the surface thereof and prevent the engagement of the clothes with the rust deposit that comes from the spray water and gravitates to the bottom of the spinning element.

It will also be apparent that the filter or protector is made of flexible and washable material so it can be reversed or cleaned from time to time and ridded of the damaging rust material.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What is claimed is:

1. A rust filter or protector for use with water spray rinse spinner-extractors comprising a pad conforming to the shape of the bottom of the spinning element of the spinner-extractor and an upstanding ring of flexible selfsupporting material secured to the outer periphery of said pad and adapted to extend upwardly against the inner surface of the spinner whereby the protector will be retained by engagement of the clothes With said ring when the clothes are radially thrust toward the spinning element surface as a result of centrifugal action.

2. A rust filter or protector for use with Water rinse spray spinner extractors as defined in claim 1, and said ring being secured to the periphery of the pad in such a manner as it can be turned therefrom in one direction or another to permit the filter or protector to be reversed upon the bottom of the spinning element.

3. A rust filter or protector for use with water rinse spray spinner extractors as defined in claim 1, and said pad being formed of annular cloth pieces with filling material disposed therebetween and stitched to provide 4. A rust filter or protector for use With Water rinse spray spinner-extractors asdefined in claim 1, and said pad being flexible and a plurality of radially-extending, angularly-spaced pocket strips secured to one surface of the pad and reinforcing strips respectively disposed in said pockets.

5. A rust filter or protector for use with water spray rinse spinner-extractors as defined in claim 2, and said pad being formed of annular cloth pieces With filling material disposed therebetween and stitched to provide a quilting assembly and a binding tape secured to the inner periphery of the assembly, and a plurality of radiallyextending 'angularly spaced pocket strips secured to the assembly and reinforcing strips respectively disposed in a quilting assembly and a binding tape secured to the 15 said pockets.
